'''Alexandra''' (aka '''Alex''') is one of the main protagonists of the "[[Totally Spies!]]" series, she is best friends and fellow spies with [[Clover]] and [[Samantha]]. She is a [[WOOHP]] agent and worked under [[Jerry Lewis]] until [[Season 7]] where she now works under [[Zerlina Lewis]].
==Biography==
[[Caitlin]] is her rival. Alex's counterpart is [[Alice, Pam, Crimson|Alice]], who is from the previous [[WOOHP]] spy team. She wears a golden yellow [[Catsuit]] on her WOOHP missions.
She went to Beverly Hills High, and then Malibu University for college studying to become a veterinarian.
Alex was born to Carmen and Doctor Casoy and inherited the spy gene, possibly from her mother. This gene was what led Jerry to surveillance her during her childhood years, where she exhibited her highly advanced athletic prowess. She started her first year of high school as a transfer student at Beverly Hills High and by fate, met her two best friends forever Sam and Clover. Alex would also make long-time rivals/nemeses with Mandy, Caitlin, and Dominique.
After being chased by giant sushi roll, Alex, Sam and Clover were transported to a strange place. Alex starts digging through a desk and pressed what looked like a stapler. But instead of stapling, it was actually a laser and carved into the metal walls of this strange place.
She then meets her boss, Jerry and his assistant, Tad. Both revealed that she was at the World Organization of Human protection, WOOHP, a secret organization that fights global crime in an effort to protect human life and Alex had been selected to join their elite group. Alex also learns that Jerry had monitored her, was behind her transfer to Bev High, and even set up the sushi roll incident as a test; which she passed. Alex was extremely against joining but began her training as a trial (and the threat of exile to Siberia if she were to reveal what she had seen). After saving the world for the first time, imprisoning Tad for betrayal, and being able to experience the thrill of spying, she decides to join WOOHP.
Over the course of her high school and college life, she had to learn how to balance her job and its secrets, social life, and academics as well as growing up.
==Personality==
Alex is a mixture between a [http://en.wikipedia.org/wiki/Tomboy tomboy] and a [http://en.wikipedia.org/wiki/Girly_girl girly girl], she is the most athletic and fitness-minded spy of the team. She loves to play sports, especially soccer, video games, and is always trying out some new fad diet.
Alex is also the most naive and absent-minded. This could be due to her being the seemingly youngest member of the group. She interprets some figures of speech literally.
Alex is also the youngest and most childish, seeing as her oldest and dearest friend is a stuffed turtle named Ollie and she has a teddy bear backpack. She is often seen as the "little sister" of the group, as Sam and Clover are the 2 "big sisters" who dominate over her. Another characteristic of Alex is that she's always about keeping her friends happy. She often serves as a peacekeeper between Clover and Sam who have meaningless squabbles ("[[Abductions]]"). Alex is also a big animal lover, and she likes petting zoos which is seen in "[[Mime World (Jazz Hands Return - Part 3)]]".
Despite being the most athletic, she tends to be clumsy, and has been prone to bad luck (Alex can be very superstitious). Alex is also the second girliest. She is very concerned about fashion and boys, to the same extremes as Clover; an obsession that Sam has trouble understanding.
Another one of Alex's hobbies is eating. Alex has a taste for Asian themed outfits and her favorite food is Chinese food (wontons, apparently). Even though she may be the most healthy of the 3 spies, she likes to eat the most. In "Evil Valentine's Day", we see that she has a dream about candy. In the beginning part of the B-story in "[[The New Jerry]]" and the ending of "[[Animal World]]", we see her eating nonstop.
During [[Season 1]] and [[Season 2]] of Totally Spies, Alex was referred to (and shown) as a bad driver (Clover made a comment at one point in [[Season 5]] indicating that it took more than 3 attempts for Alex to get her driver's license), but in [[Season 3]], [[Season 4]], and [[Season 5]], she was the one normally behind the wheel (indicating that her driving skills had improved). However, in [[Season 7]] in "[[Creepy Crawly Creature Catcher]]", Alex show again her bad driving, when she tries to drive the [[WOOHP-e]] causing choas in WOOHP World, but that's probably because it was a flying car.
==Physical Appearance==
Alex is a teenage girl with beautiful brown skin varying from [http://cartooncharactersinfo.com/light-skin-cartoon-characters/ light] to dark, sleek black hair in a chin-length bob cut with locks that sit at her cheeks, framing her face, light honey-brown eyes, and wears rose pink lip gloss. Her hair is parted in the middle with two small loose strands protruding in between, however her bangs would be inconsistently unruly on either side regardless of where she's facing, similar to [[Clover]]. Notably, when her hair is wet, it falls down just past her chin. Despite her bobbed hair, it can be styled in many styles as seen in various episodes (such as "[[Déjà Cruise]]", into being a straight bob cut similar to Clover's, but straighter and with different bangs, a Mohawk, and even medium length voluminous waves). She's also been shown wearing it in ponytails and buns as well. She is often shown to wear hair accessories as well, such as hair clips and scarves. She's shown to wear earrings at times as well. When wearing the Mali U costume, she wears a skirt (a shorter version of the actual mid length dress). She also has freckles/marks on her cheeks. She wears a yellow [[catsuit]].
She appears to be mixed race, though it’s never completely clear if her ethnicity is [http://en.wikipedia.org/wiki/United_Nations_geoscheme Central America, Caribbean, South America, Southern Asia, Southeastern Asia, Eastern Asia] or a combination. In "[[Alex Gets Schooled]]" her dad is shown to be white and her mom appears to have a darker complexion and is named Carmen, which is commonly associated with the Hispanic community. However, one of the producers confirmed Alex is of mixed South Asian and Latin American descent. Over time, her father appears with a complexion similar to Alex (dark brown) in Season 6 which and her Mother´s complexion changes slightly, in Season 4 her mother´s shade changed from a pretty almond-brown to a similarly pretty honey-brown complexion in "[[Totally Busted]]" with her hair being changed to Alex's hair color as well. Alex has a taste for Chinese themed outfits, and her favorite food is the Chinese food of wontons.
In "[[Game Girls]]", Alex also wore a blue/silver catsuit.
Alex has the broadest variety of clothing out of the group. Usually she dresses trendy and girly like Clover, or preppy and elegant like Sam, or in a sportier type of outfit. She usually wears heels or flats, but often she wears sneakers as well as boots. She's also shown to like wearing Giant Panda pajamas in some episodes. She also wears a lot of Chinese outfits and other Asian inspired clothes. She is also seen wearing a kimono in [[Evil Heiress Much?]].
She is the only one of the 3 girls whose bathing suits seen are all bikinis except for her blue/silver one piece bathing suit from "[[Game Girls]]". In "[[The Getaway]]" and "[[Alex Gets Schooled]]", she wears a yellow bikini with a yellow pair of shorts. In "[[The Eraser]]", she wears a green bikini with a skirt. In [[Mommies Dearest]], she wears a pink version of the yellow bikini with shorts. She is wearing another yellow bikini in "[[Super Nerd Much?]]" which is similar to the green bikini she wore in "Eraser". In "[[A Spy is Born I]]", it's revealed that Alex is the shortest member in the group, but in "[[Escape From WOOHP Island]]", she's taller than Sam, Clover, and Britney. In "[[Ho-ho-ho-no!]]" both she and Clover are taller than Sam.
In [[Season 1]], her primary outfit was a lime green sl
